Features

Overview: Bose SIE2 in-ear sport headphones are designed
specifically for exercise, both indoor and outdoor. They offer the same audio
performance as other Bose in-ear headphones, but can withstand the rigors of an
active lifestyle. They have been optimized to resist moisture from the weather
or from sweat. The StayHear silicone tips fit comfortably, but snugly into your
ear, and are designed to stay in place during strenuous activity.

StayHear Ear Tips: The SIE2 headphones include three sizes
of silicone ear tips (S/M/L) to assure a more accurate fit that's comfortable
and stable. Advanced
materials and design allow the tips to nestle inside the bowl of the ear, while
also naturally conforming to the ear's upper ridge. StayHear tips also are
designed to remain more securely on the headphone, as well.

Note: You should not
attempt to wear the headphones without the ear tips.

TriPort Technology: Like other Bose in-ear headphones, the
SIE2 sport headphones feature Bose's acclaimed TriPort technology. The
headphones deliver wide-range sound, with deep, natural lows and crisp highs. Even though they
are in-ear headphones, the SIE2 are not noise-canceling. They are purposefully
designed to keep you aware of your surroundings while you are running through
busy city streets or highways.

Cable and Extension: The SIE2s have a 32" cable that's long
enough to reach your portable media device, and short enough that you're not
constantly fighting excessive length. A clothing clip is attached to the cable
so you can keep it out of the way. If you need additional cable, a 21" extension
is included.

3.5mm Connector:
The headphone cables have a slender, straight 3.5mm plug that fits directly into most digital media players, including
iPod and iPhone models with hard cases, as well as laptops and portable CD and DVD players.

Armband:
Included with the SIE2 is a matching green and gray Reebok fitness armband that
holds your device during exercise. It can hold your iPod, iPhone, or most any
portable media device. It has a clear window to let you see the device's screen
and operate the touchscreen controls. There's also a separate pocket for your
keys.

Big Sound!

These headphones sound great! They truly live up to the Bose standard and are a must have. I was a little leery at first about the fit and whether they would stay in my ear, but they have proven to stay in no matter what I am doing. The durable design and great look are a bonus and I am pleasantly surprised with these headphones.

The only drawback is the amount of noise canceling. I thought they might isolate outside noise a little better. I mainly wear these while riding my bike and do experience a lot of wind noise wearing these as opposed to other headphones past, but it is not that big a deal to me.

Overall, a wonderful product worth the price!

Pros:Great, full sounds. Durable and stylish headphones that stay in the ear not matter the activity.

Product reviews from the Crutchfield Labs

Innovative design and function

I sometimes have a problem with in-ear headphones; I can feel them gradually slipping out of my ears. Not a problem with the Bose® SIE2 sport headphones. Rather than rely on a tight seal inside the ear canal to hold the earbuds in place, the StayHear® tips direct the sound into the ear through a silicone tube, and the earbud sits outside, securely held by a support that fits in the outer part of the ear.

Sure, other sports headphones use a similar solution, but the silicone in the SIE2 is the softest and most flexible I've experienced. So the earbuds slip right into place, perfectly shaping themselves to the contours of my ears. I never felt like they were slipping. Actually, after a while, I just forgot they were there (except for enjoying my music, of course).

The sound quality was excellent. I heard a lot of detail in my music, even when playing it at relatively low volumes. An all-around great set of sports headphones.
